TIoN or MICHIGAN -PULIIER My inventionv relates to pullers and has among its other objects the production of devices of the kind described, which are sim le,

convenient, compact, eilicient and satis actory for use wherever found applicable. A particular object of the inventionis to provide improved means for the removal or dismantling of concrete form ties after the concrete has been poured, but the invention is limited to such use onl in so far as deiined in the appended claim. any other objectsv and advantages vof the construction herein shown vand described will be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the,

bination of parts herein shown and described, and more particularly pointed out in the claim.

In the drawings, wherein like reference characters indicate like or corresponding parts; p

Fig.. 1 is a side view partly in section of a puller embodying the invention, the puller being shown in connection 4witliparts of a concrete forni tie which it isadapted to dismantle; Y

Fig. 2 is an end elevation of the improved puller as it appears when looking from the ri htinFig.1;

ig- 3 is a section taken on linev33 of Fig. 1; A

ig. 4 is a view similar to Fig. 1 of a puller embodying another form of the invention, the puller being `shown in connection with parts of a conci-ete form tie which'it is adapted toi invention. The puller 25 preferably com dismantle;

Fig. 5 is la fra entary plan view of the apparatus shown in Fig. 4; and

' Fig. 6 is a section taken on line 6-6 of I' GRAND mins, MICHIGAN, A conrona- I' a rod 11 having a head 12 at one end thereof and having'its other end threaded as at`13 to Vengage a member 15.' The member 15 is preferably provided with a lug 16 which extends from the longitudinal center thereof and terminates in an over-hanging tongue 17. The

tongue 17 extends laterally from the'central portion of the lug 16 and projects beyond the outer surface of said lug. The lug 16 and -the tongue 17 may be inserted in the open end of a conical housing 19.. forming part of the above-mentioned concrete form. As described in the copending applications, the open end ofthe housing 19 is provided with an inwardly projecting lug 20 which may be engaged by the `tongue 17 when the housing 19 is to be removed from the concrete. The housing 19 is imbedded inthe concrete When the concrete is poured and in most instances it is desirable to remove the housing for further use.

Slidably mounted u on the rod v11 is a weight 14 which may be manually reciprocated to strike repeated blows upon the head 12. In the operation of my improved puller, the lug 16 and tongue 17 .may be inserted in the housing 19 a suliicient distance to permit vthe tongue to` be brought into engagement eren'ce character 25 designates generally a puller which embodies another form of the prises a rod 26 having a head 27 at one end thereof, the other end of the rod being threaded as at 28 to permit the rod to be secured to a member 29 provided with bifurcations 30.` 5

,2 `v z V aymara The member 86 is adagetled to project through ,a wooden form mem 87 m such manner' thatawiretieimaybesecuredtoitsinner end. The u of this construction is s clearly set ort in the co-pending applications and in said applications I have described how the wire tie 39 may be severed afr the concrete has been poured. After the wire tie 89 has been severed, the member 36 10 may be readily withdrawn from the concrete b y em loying a puller embodying my invention. us, the shoulders 83 may be enga ed with the lugs 34 in the manner illustrate in Fig. 4 and the weight 31` ma7 be manually 15 operated to strike repeated b ows upon the head 27 until the member 3,6 is loosened from the concrete.

Having thus described my invention, it is obvious that various immaterial modificazo tions maybe made in the same without de- Eart' from the spirit of my invention; enoe do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts as herein shown and described or uses mentioned. y

What I claim as new and desire to secure by Letters Patent is:

In a tool of the character described, a rod 80 having one end formed with a head, a cylindrical member havin a threaded connection with the other end o the rod, said member having a longitudinal projection in substanv tial alignment with said rod, a transverse en- 85 largement projecting laterally from said longitudinal projection and in spaced relation to the adjacent end of said c lindrical member, and a hammer member s 'dably mounted on said rod. 4o In testimony whereof, I have hereunto signed my name.
